Carnation plant named ‘Yoder Flash’

ABSTRACT

A distinct cultivar of  Carnation  plant named ‘Yoder Flash’, characterized by its bright red-colored flowers; strong flowering stems; strong calyxes that resist splitting; good postproduction longevity with flowers maintaining good substance and color for about ten days in an interior environment after shipping; and resistance to  Fusarium oxysporum .

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘Yoder Flash’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophyllus and hereinafter referred to by the name ‘Yoder Flash’.

The new Carnation is a product of a planned breeding program conducted by the Inventor in Salinas, Calif., and Madrid, Cundinamarca, Colombia, South America. The objective of the breeding program is to create new cut Carnation cultivars having long flowering stems, early flowering, attractive flower color and good flower form and substance.

The new Carnation originated from a cross-pollination made by the Inventor in 1997, in Salinas, Calif., of the Carnation cultivar Nelson, not patented, as the female, or seed, parent, with the Carnation cultivar Bourbon Street, disclosed in U.S. Plant Pat. No. 10,063, as the male, or pollen, parent.

The cultivar Yoder Flash was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Madrid, Cundinamarca, Colombia, South America in July, 1998. The selection of this plant was based on its flower color and good flower form and substance.

Asexual reproduction of the new Carnation by terminal cuttings in Madrid, Cundinamarca, Colombia, South America since August, 1998, has shown that the unique features of this new Carnation are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yoder Flash has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yoder Flash’. These characteristics in combination distinguish ‘Yoder Flash’ as a new and distinct cultivar of Carnation:

-   -   1. Bright red-colored flowers.     -   2. Strong flowering stems.     -   3. Strong calyxes that resist splitting.     -   4. Good postproduction longevity with flowers maintaining good         substance and color for about ten days in an interior         environment after shipping.     -   5. Resistant to Fusarium oxysporum.

Plants of the new Carnation can be compared to plants of the female parent, the cultivar Nelson. In side-by-side comparisons conducted in Madrid, Cundinamarca, Colombia, South America, plants of the new Carnation and cultivar Nelson differed in the following characteristics:

-   -   1. Plants of the new Carnation were about 5 to 105 cm taller         than plants of the cultivar Nelson.     -   2. Plants of the new Carnation had slightly larger flowers than         plants of the cultivar Nelson.     -   3. Plants of the new Carnation were more resistant to Fusarium         oxysporum than plants of the cultivar Nelson.

Plants of the new Carnation can be compared to plants of the male parent, the cultivar Bourbon Street. In side-by-side comparisons conducted in Madrid, Cundinamarca, Colombia, South America, plants of the new Carnation and the cultivar Bourbon Street differed in the following characteristics:

-   -   1. Plants of the new Carnation were about 5 to 10 cm taller than         plants of the cultivar Bourbon Street.     -   2. Plants of the new Carnation flowered about one week later         than plants of the cultivar Bourbon Street.     -   3. Plants of the new Carnation had brighter red-colored flowers         than plants of the cultivar Bourbon Street.

Plants of the new Carnation can also be compared to plants of the cultivar Tanga, not patented. In side-by-side comparisons conducted in Madrid, Cundinamarca, Colombia, South America, plants of the new Carnation and the cultivar Tanga differed in the following characteristics:

-   -   1. Plants of the new Carnation flowered about two weeks earlier         than plants of the cultivar Tanga.     -   2. Plants of the new Carnation were more freely flowering than         plants of the cultivar Tanga.     -   3. Plants of the new Carnation had stronger calyxes than plants         of the cultivar Tanga.     -   4. Plants of the new Carnation were more resistant to Fusarium         oxysporum than plants of the cultivar Tanga.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Madrid, Cundinamarca, Colombia, South America under conditions which approximate commercial practice in a single-layer polyethylene-covered greenhouse. Four-week old rooted cuttings were planted in ground beds and pinched about three to four weeks later. During the production time, day temperatures ranged from 19° C. to 24° C.; night temperatures ranged from 4° C. to 12° C.; and light levels ranged from 3,000 to 5,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems about 27 weeks after planting.
